TOKYO--()--Toshiba Corporation's (TOKYO:6502) Storage & Electronic Devices Solutions Company today announced the launch of“TLP5214A,” a new smart gate driver photocoupler for use in driving medium-power IGBTs and power MOSFETs that delivers desaturation sensing characteristics that improve on those offered by the current “TLP5214”. Mass production shipments start today.

TLP5214A newly integrates such features as desaturation leading edge blanking time, filtering time, and optimization of soft turn-off performance. These contribute to secure execution of applications by suppressing short-time pulse noise during switching and desaturation sensing.

The latest Gartner market report recognizes Toshiba as the leading manufacturer of optocouplers by sales in 2015 and 2016, with 23% of sale-based market share in CY2016. (Source: Gartner “Market Share: Semiconductor Devices and Applications Worldwide 2016” 30 March, 2016)

Toshiba will continue to deliver products that meet the needs of customers by promoting the development of a diverse portfolio of photocouplers and photorelays tailored to market trends.
